He was the guy that flew the Texas flag outside his Elliot House dorm (FDR's old crib) for four years and drove that beatup red pickup truck.
He is credited with introducing Pace Picante Sauce and tortillas to those Eastern dudes and regaling them with fictious tall tales about Texas that they ate up almost as fast as their nachos.
One major downside of his stay at Harvard that I've had to deal with is a picture of him wearing a bowtie and white shoes at some function.
